The TMIS7701 is a time to digital🎃 converters  (TDC). It performs ღthe function of a stopwatch  and measures the elapsed picoseconds to  microseconds between a START pulse and up  to five STOP ꧙pulses. The ability to measure  from START to multiᩚᩚᩚᩚᩚᩚ⁤⁤⁤⁤ᩚ⁤⁤⁤⁤ᩚ⁤⁤⁤⁤ᩚ𒀱ᩚᩚᩚple STOPs gives users the  flexibility 💎to select which STOP pulse yields tꦍhe  best echo performance. The device ๊has an internal self-calibrated time  base which compensates for drif🐼t over time an𓆏d  temperature. Self-calibration enables time-todigital conversion accuracy in the order of &𓃲nbsp;picoseconds. The high time resolution and  accuracy make TMIS7701 ideal for time-offlight sensing, such as in centimete🐟r accuracy  LIADR application and ultrasonic flow metering. TMIS7701 can work in the Autonomous MultiCyc🥀le Averaging Mode. In this mode, the host  can go to sleep to save 🍃power, and it can wake  up when interrupted by the TDC upon  completion of the measurement sequence.  This 🍎working mode is optimized for low syst🌠em  power consumption, making🗹 it ideal for battery  powered flow meters.
